Raul Ruiz said that like America cinema has been discovered many times. The same can be said for semiotics, and for the notion of the arbitrariness of the sign. Platos dialogue on semiotics, Cratylus, considers arbitrariness in his idea that some signs - in particular words - signify by convention (thesei) rather than by nature (phusei). I assume the scholastic semioticians would have been familiar with this topic too - Rabelais certainly has Panurge parody the rather arbitrary signs of an English semiotician and outdo him in a signifying contest. Semiotics seems to have been a notoriously English enthusiasm back then. Locke wrote some fascinating things on arbitrariness in his Essay. Hegel did too in his Encyclopaedia I think. Peirce too. Husserl too. Even Humes (independant?)rediscovery of the Aristotelean taxonomy of kinds of association could be seen as another consideration of arbitrariness - again under the concept of convention or custom. I am not sure but I suspect that, like Columbus, Saussure made the innocent mistake of thinking that he had discovered the science of and the arbitrariness of signs. Certainly many after him thought he was the first to bump up against this great philosophical and much trodden continent. Arbitrariness is a wonderfully puzzling concept. People may say that arbitrary signs should not be confused with conventional signs. I would risk a quick translation of arbitrary as that which contains a more convoluted and cryptic historical genesis than we can untangle. At least, that is an expalntion of why what we call arbitrary strikes us inexplicable other than by custom. But to turn from this to film. Film as moving image seems to be the antithesis of an arbitrary sign. As Ruiz says (and Bazin, and many many others) it is part of the long tradition of capturing images, virtual realities, total cinemas. Still, there is no doubt that in the history of cinema it has been seen as part of its maturation that arbitrary signs - conventions - quickly became available to signify things that were otherwise incommunicable. Dissolves, fades, certain emblematic uses of images, and most importantly, even the very cut between shots contain their portion of arbitrariness. Montage as opposed to mise en scene might be seen as that which entails and facilitates arbitrariness in cinematic signification. Meanwhile cinema is such a non arbitrary semiotic medium that, in its mis en scene and its sound track, it is always just showing arbitrary signs (eg speech, writing, etc) as its second nature. Ross
